A power steering rack is a central component of a vehicle’s steering system that helps convert the driver’s steering input into smooth, controlled wheel movement with the assistance of hydraulic or electric power. Housed within the steering rack assembly, the rack and pinion mechanism works alongside power assist (hydraulic fluid or an electric motor) to reduce the effort needed to turn the steering wheel, especially at low speeds or while parking.

The power steering rack is connected to the steering column, tie rods and front wheels, making it essential for accurate and responsive steering. When it starts to wear out or develop leaks, drivers may notice stiff steering, fluid leaks, uneven tire wear or noises while turning. A failing power steering rack can severely compromise driving safety and comfort, so prompt diagnosis and replacement are important to maintain proper steering function and road control.
